JOHN A. STONE, OF CHICAGO, ILLINOIS, ASS-IGNR TO INTERNATIONAL HARVESTER 00M- conN-nanvns'ran. Y

v To all whom. it may concern: i' I Be it. lknown that I, JOHN A. STONE, a citizen of the United States, residing at Chicago, in the county of (700k and State of Illinois; have invented vcertain new and useful Improvements in (loi'nfHarvesters, of which the -ollowing is a specification.

My invention relates tov improvements in coi-n harvesters ofthe type wherein means are provided for severing the ears from the standing stalks and Adelivering them to a husking mechanism, from which they are conveyed to any suitable receptacle; the objects of my invention bein@r to provide improved means for guiding an( advancing the stalks toward the ear severing mechanism; to means fordelivering the severed ears -to the ear conveying and elevating mechanism; to

means for transmitting motion to the ear conveying mechanism; to means for relieving the husking mechanism from danger of becoming clogged from vany accumulation -of loose stalks or leaves that may be carried up by the ear conveying mechanism; to means lfor automatically unclutching the -husked corn elevator mechanism from its motion transmitting means when the elevator chute has been raised to a predetermined limit, and to other details of construction that will be described in the specification and illust-rated in the accompanying drawing, in Which- Figure 1 is a side elevation ofa part of a corn harvester in which my invention finds an embodiment; Fig. 2' is a cross section, along line AB of Fig. 1, in the `direction'of the arrows; Fig. 3 is a top lan view of Fig. 1 Fig. 4 is a cross section aibng line C-D of Fig. 3, in the direction of the arrows; Fig..5 is a cross 'section along line E-F of Fig. 3, and represents the details of construction in connection with the loose stalk and trasliseparating mechanism; Fig. 6 is a cross section along line G-H of Fig. 3, and represents in detail a part of the motion transmitting means in connection with the ear conveying mechanism; Fig. 7 is an end elevation of a part of the machine and designed to illustrate the connection between the husking mechanism and the husked corn elevator, and

severing mechanism; Fig. 9 is a cross section; g alonglthe line K-L of a part of Fig. 7, show# ing t e delivery end of t e husking mechanism, the receiving end of the husked cornele Y mechanism connected withthe latter;

10 is a detached detail, partly in section, of the clutch shipping mechanism shown in Fig. 9; and Fig.V 11 is a detail of the clutch shipping fork as connected therewith; and Fi 12 is a top lpgan view of the ear severing roll ers and sta advancing mechanism.

The same reference characters designate like arts throughout the several views.

T e carrying and traction wheels are re resented b the numeral 1, and 2 is the Xie upon whic they are mounted.

A main frame, including angle bars 3 and 4, is supported upon said axle and arranged to receive the operative parts of the machine in a manner to substantially equalize the JI5 weight thereof upon oposite sides -of the axle. The frame is inclined upward from front to rear, and at its forward end is ada t ed .to straddle a row of corn as shown in t ig. 12. Gathering chains 5 are mounted upon opposite sides of the corn passageway and are provided with a common form of fingers -6 adapted to engage with the stalks and properly advance them toward the ear severing mechanism, which mechanism includes snag ping rollers 7 and 8, mounted -upon the rig and left-hand sides of the "passageway, 'respectivelv, and inclined upward and reax-, ward. he rollers are .provided with tapering forward ends, which have spirally arranged ribs 9 thereon that are adapted .to convey the stalks rearward. The roller 7 and the ear severimr portion of roller 8 are rotated in op osite directions and o erate to feed the sta ks downward between t em and to sever the ears therefrom by contacting with. their butt ends in a common Wa The tapered portion 10 at the orward end of roller 8 is rotated in a direction opposite to that-of the body of the roller and in the same direction as roller 7, it being preferabljournaled upon the extended end of a sha 11 that forms'a core for the bod of roller 8, and is provided with a toothed7 portion 112 that envases with motion transmitting gears that will be described later.

The function of the tapered portion of the rollers with their spirally arranged ribs is 4to engage withfallen stalks and raise and advance them toward the ear severing portions, and if they are caused to rotate in opposits directions, the same as the body portions thereoand the ribs should come in contact With'an ear of corn,`their action is so ag essive that'the ear will-be drawn down an operated' upon in such a manner as to shell more or less of the corn. W'hen the i tapered ends .of the rollers are rotated in the l chain 14having ear engaging rakes 15 carried thereb and 16 designates an can deilecting ro er mounted upon the same side of the passageway and in a plane above that of roller 8 and having its axis inclined toward 25 the opposite side of the passageway as it exten s upward and rearward.

The roller extends be ond the forward ends of the ear severing ro ers, and that ortion of the roller has a greater diameter t an its rear portion and is provided with a spirally arranged rib 17 adapted to assist in raismgallen stalks and conveying them rearward.

Motion is transmitted to the several operative rollers from the source of power by means including a longitudinally arranged shaft 18 mounted upon the frame in 'rear of the rollers, and having at its forward end clutch mechanism 19 whereby it is operatively connected with the rear end of the journal of roller 8. The rear ends of the Yrollers are journaled in a cross-plate '20, se-

cured to the frame members 3 and 4, and in rear of said cross-plate there is secured to the V journal of roller 8 a pinion 21, that engages with a corresponding pinion 22 secured to the journal of roller 7 and also with ain ion' 23, secured to the journal of the de ecting roller 16. Pinion 23 engages With and trans- I mits motion to a pinion 24, secured to a sup- Elemental longitudinally arranged shaft 25,

avi-ng its forward end journaled in the crossplate 20, and its rear end in a bracket 26, Asecured to the machine frame.

Pinion 24 engages with and transmits motion to a pinion 27 secured to a longitudinally arranged shaft 28, having its rear end journaled in the crosslate 20, and extendi forward is journaled 11n bearings supporte by a bracket 29 secured to a. fixed part oi the machine; said bracket being provided with a journal bearing 30 arranged at right angles and located intermediate the bearings for the shaft, and in which is journaled a shaft 31,

having secured to its lower end a bevel gear toward eac 32., en aging witha bevel pinion 33, secured n Y to sha t 28;.and securedto the opposite end of shaft 31 1s a sprocket wheel 34Yeng'aing\ -yvith and transmitting vmotion to the gat er- A' u mg cham 5 upon the same side of the com 7d `roller is ournaled, extends orward and is journals in a bracket 39, secured to frame 30 member 4.

Motion is communicated to the ear conv veymg chain 14 by means of a bevel gear 40,l secured to one end of a short transverse shaft 41, journaled in a sleeve 42, forming g5 part, of a bracket 43, secured to frame memer`3, and having longitudinal bearings 44, m Wlnchis journ edshaft 18, and secured to shaft 181s a bevel pinion 45 engaging with the, gear 40. Secure to the opposite end of shaft 41 is a toothed clutch member 46 adapted to engage with a corresponding toothed clutch member 47, secured to a shaft 48.

The clutch member 47 is rovided with a 95 sleeve portion that is journa ed in a bearing 49 secured to a fixed part of the machine, and is adapted to have a longitudinal movement therein, and its inner end has a' conical head 50. Secured to the opposite end of shaft 48, 1in a manner to rotate therewith and have a. limited longitudinal movement thereon, is a sleeve 51, by means of the in 51l passing through a slot in the sleeve, ti e latter having at lts inner end a conical heed 52 correspond- 105 in with the head.50, and the sleeve is journa ed in a bearing 53 sup orted by a fixed part of the machine, an is also provided with a counterbore portion adapted to receive a coiled spring 54, that surrounds a reduced portion of the shaft and operates bev tween an adjusting nut 55 and the sleeve in a manner to 1yieldingly press the conical heads other. Y

A sprocket wheel 56 is journaled upon the 115 the inner ends of the sleeves, is engaged with the chain 14, and is provided with an interior annular ring 57 adapted to rictionallyengage with the opposing conical heads of the sleeves in a manner to be driven thereby, and 12 the amount of fessure upon the friction members is reg ated by means of the adjusting nut 55.

Y By means of the above described frictional drive for the ear conveyer, all danger of damage to its operative parts, due to accidental clolgging, is avoided.

the operation of the machine under cer-- tain conditions of crop, a large amount of loose leaves and broken stalks is delivered to the ear conveyer along with the ears, and if allowedto pass to the huskmg mechanism will pair of transverselv operati ng relief rollers 58,

that are journaled in brackets 59 and 60 secured to fixed parts of the machine frame; the lower rollerbeing operatively connected with the longitudinal shaft .18 by means of a bevel pinion 61, secured to saidshaft, and a similar pinion 62 secured to the vprojecting end of the shaft of the lower roller; the upper roller beingr driven in an opposite direction by means of the pi'nions 63 at the opposite ends of the rollers and adapted to engage with each other. In operation the rollers engage with any loose leaves or stalks that are. carried 'up by the chain 14, and separate them from the ears that are delivered over the end of chute 13, and into a transversely arranged chute 64, at the rear of the machine, that is inclined upward to the receiving end of a series of husking rollers 65,'mounted in a frame 66, that is inclined downward toward the receiving end of a husked corn conveyer and delivery chute 67.

The unhusked ears are conveyed to the husking mechanism by means of carrier chains 68, operating at the bottom of V shaped channels 69, that are formed in the bottom of chute 64; the channels upon opposite sides of the central one diverging cuti s aft 74 .at the up ward and upward for the purpose of delivering the ears to separate pairs of husking rollers.

.A transverse shaft 70 is journaled at the lower end of the husking mechanism frame 66, and the corn delivery chute 67 is pivotally mountedA thereon in a manner permitting its outer and delivery end to beraiscd or lowered as may be required. Motion is communicated to the shaft 70 by means of a sprocket vwheel 71, and a chain 72 engaging with a s rocket wheel-73, secured to a transverse per end of the frame 66 4 carrying'the huskmg mechanism.

The s aft 70 communicates motion to an ear conveying chain 75, having rake members 76 secured thereto; the mechanism being ada ted to convey the husked ears up ward to t e delivery end of the conveyer.

It is desirable, 1n the operation of machines of this character, to provide means whereby the ear elevating and delivering mechanism may be temporarily' thrown out of action, as in turning at the corners of a eld, or when the corn receiving wagon is not in position to. receive the corn. To effect this result I provide mechanism as follows: The sprocket'wheel 71 'is adapted to have longitudinal movement upon the shaft 70, and is provided at the outer end of its hub with clutch teeth 7 7, that are adapted to engage4 with a pin extending transversely through said shaft; and the inner end of thev hub is provided with a peripheral 'groove 79 that is adapted to receive a clutch shipping eratively connected with a crank 81 at the Vfork in a common way'and which is'opf A lower end of a vertically arranged shaft82,

that is pivotally attached vto thefframe 66; the. upper end of the shaft being provided with a crank arm 83 secured thereto, and,` to'f" which is pivotally connected one endof a link 84, the opposite end of said-link being ivot' j ally connected with a hand lever 85, tiat'is' pivotally mounted upon the frame 66 within convenient reach of an operator inthe seat 86. When the ear elevator chute is folded' for transportationv purposes, the car convey#l ing mechanism is thrown out of action, which may be effected bythe means as described; but should the chute be accident-allyv raised beyond a predetermined limit in the operation of the machine and the operating mechanism be thereby subjected to undue strain, liable to cause breakage to occur, I have provided means that will o rate automatically to disengage the clutc mechanism when such limit of the chutes movement has been reached; the means consisting in providing an extension 87 to the crank arm 83, and ,a bracket S8, secured to the side of the chute 67, is adapted to contact therewith in a manso' p ss n ner to rock the shaft 82 in' its bearings and disengage the clutch mechanism temporarily rounding the shaft 7() and operative etween the hub of the sprocket wheel and the end of i the bearing for the shaft to normally hold the clutch members in engagement.
